WORK-CARRIER.

SPECIFICATION forming part of Letters Patent N0. 770,051, datedSeptember 13, 1904. Application filed January 15, 1904. Serial No.189,146. (No model.)

To all whom, it may concern:

Be it known that I, GEORGE A. ENSIGN, a citi zen of the United States,and a resident of Defiance, in the county of Defiance and State of Ohio,have invented a new and Improved Work-Carrier, of which the following isa full, clear, and eXact description.

The invention relates to wood-working machines, such asmortising-machines, boringmachines, and the like; and its object is toprovide a new and improved work-carrier arranged to havea limitedsliding motion between adjustable stops or a free unlimited slidingmotion for any desired distance independent of the stops. I

The invention consists of novel features and parts and combinations ofthe same, as will be more fully described hereinafter and then pointedout in the claims.

A practical embodiment of the invention is represented in theaccompanying drawings, forming a part of this specification, in whichsimilar characters of reference indicate corresponding parts in all theviews.

Figure 1 is a side elevation of the improvement as applied to the mainframe of a woodworking-machine. Fig. 2 is atransverse section of thesame on the line 2 2 of Fig. 1. Fig. 3 is a front elevation of the same,and Fig. 4 is a longitudinal sectional elevation of the same on the line4 4 of Fig. 3.

In mortising, boring, or otherwise working wooden articles onmortising-machines, boring-machines, and the like the bed carrying thework is arranged to have a limited sliding motion sidewise as well astransversely, and

for this purpose suitable stops are provided, so that the articlestreated are uniform as to the size and shape of the mortises, bores, &o.It is, however, frequently desirable that the bed and its Work is givenunlimited movement in either direction for the time being Without,however, disarranging the stops, and in order to allow such movement thefollowing arrangement is made.

The bed A for carrying the work to be operated on by the usual tools ofthe machine on which the device is used is mounted to slide sidewise onguideways secured to or forming part of a slide B, mounted to slidelongitudinally on guideways held on a support or bracket O, secured toor forming an integral part of the front of the main frame I) of themachine.

On one side of the bed A (see Fig. 1) is formed alongitudinally-extending bearing E, in which is mounted to turn a shaftF, carrying at its forward end a handle F, adapted to be taken hold ofby the operator for turning the shaft, and on the rear end of the saidshaft F is secured an abutment G, adapted to move in engagement at itsfront and rear faces with stops H and H in the form of screw-rods,screwing in stop-blocks H and H mounted to slide transversely on atransverse guideway I, attached to and forming part of one side of thesupport O.

The stop-blocks H and H are adapted to be moved toward and from eachother on the guideway I to bring the stops H and H the desired distanceapart, and when the stop-blocks have been adjusted then they are clampedin place by clamping-screws K and K. The screw-rods forming the stops Hand H can be screwed in or out in the stop-blocks H and H to obtain aminute adjustment of the stops, and then the screw-rods are clamped inposition in the stop-blocks by clampingscrews J and J, as plainlyindicated in the drawings.

For the purpose described the nuts in which screw the screw-rod stops HH are split in the direction of the length of the nuts, and the splitmembers of the nuts are engaged by the clamping-screws J J. ening theclamping-screws J or J the split members of the nut spring apart bytheir own resiliency to allow screwing of the screw-rod stop H or H ineither direction-that is,

Now in loos- 5 toward or from the abutment Gand after 9 By thearing-screws K and K, and then the screw-rod stops H and H are adjustedin the said stepblocks, as above described,to obtain minute adjustment,and hence bring the stops in proper relation to the front and rear facesof the abutment G to limit the transverse sliding movement of the slideB, bed A, and the work carried thereon.

hen it is desired to give an unlimited sliding movement to the slide B,the bed A, and the work thereon, then the operator swings the handle Fupwardly to turn the shaft F and to swing the abutment G out of the pathof the stops H and H to allow the slide B to travel independent of thestops to any desired position, and with it the bed A and the Workthereon, without disturbing the position of the stops H and H. A similararrangement of stops and abutments is had between the bed A and theslide B, so as to limit the sidewise sliding movement of the bed A andthe work thereon relative to the slide B .or to allow of sliding the bedA and the work carried thereon any desired distance on the slide Bindependent of the stops and abutments. The construction of the stopsand abutments is slightly varied relative to the abutment Gr and stops Hand H above described; but the same result is obtained.

The front face of the body A is formed with a transversely-extendingguideway A, on which are adjustably held the blocks L and L, adapted tobe moved toward and from each other and adapted to be secured in placeby clamping-bolts L and L engaging the guideway A and the blocks L andL. On the blocks L and L are mounted to swing up and down the arms NandN, carrying stops 0 and O in the form of screw-rods screwing in the saidarms for obtaining a minute adjustment of the stops 0 and 0 after theblocks L and L are secured in position on the slide B. After the saidscrew-rod stops 0 and O are adjusted they are clamped in place in thearms N and N by clampingscrews P and P, the same as the screw-rod stopsH and H, and are locked in the blocks H and H by the clamping-screws Jand J.

The stops 0 and O are adapted to abut against the faces of abutments Qand Q, secured to or forming integral parts of the slide B. When thearms N and N are in a vertical position, as illustrated in Figs. 3 and4, then the stops 0 and O are in alinement with the abutments Q and Q,and consequently the sidewise movement of the bed A and the work thereonis limited; but when it is desired to give an unlimited sidewisemovement to the bed A then the operator swings the arms N and N upwardto move the stops 0 and 0 out of alinement with the abutments Q and Q,and consequently the bed A can be shifted sidewise, independent of thestops and abutments.

The device is very simple and durable in construction and can be readilyapplied to various machines, it being understood that the means employedfor moving the bed A sidewiseon the slide B and for moving the lattertransversely on the support C may be of any approved construction.

By constructing the two sets of stops in the manner described theoperator standing in front of the machine can readily operate either setwithout leaving his position that is, he can readily swing the arms N Nupward to move the stops 0 and 0 out of alinement with the abutments Qand Q or he can turn the handle F to swing the abutment Gr out of thepath of the stops H and H. By making the stops H H and O O in the formof screwrods it is evident that after the blocks H H and L L areadjusted and fastened in place the operator on loosening theclamping-screws J J and P P can screw the stops H H and O 0 toward orfrom the corresponding abutments to obtain an accurate setting of thestops. WVhen this has been done, the clamping-screws J J P P are screwedup to securely lock the stops in place.

Having thus described my invention, I claim as new and desire to secureby Letters Patent 1.
